[0067] In this embodiment, the washing device includes a water purification device 1, a washing cavity, and a control device 2. The control device 2 is connected to the water purification device 1. Specifically, the water inlet of the water purification device 1 is connected to an external water source of the washing device (such as a municipal water source, the water outlet of a water heater, etc.). The water outlet of the water purification device 1 is communicated with the washing cavity. Among them, no water tank is provided between the water outlet of the water purification device 1 and the washing cavity, and the water discharged from the water purification device 1 directly flows into the washing cavity. In other embodiments, a water tank can also be provided between the water outlet of the water purification device 1 and the washing cavity; or, the water inlet of the water purification device 1 is communicated with the water tank in the washing device.

[0068] Specifically, referring to Figure 1 , the water purification device 1 includes a first flow path and a second flow path. The first flow path is not provided with a filtering module, and the second flow path is provided with a filtering module 11. In this embodiment, the filtering module 11 is a physical filtering module 11, such as a filter screen, for filtering solid particle impurities (such as sediment, rust, etc.). In other embodiments, the filtering module 11 can also be a chemical filtering module 11 for filtering impurities in water through chemical reactions.

[0069] The water inlets of the first flow path and the second flow path are both communicated with the water inlet of the water purification device 1, and the water outlets of the first flow path and the second flow path are both communicated with the washing cavity. The water flowing into the water purification device 1 can flow into the washing cavity through the first flow path and / or the second flow path.

[0070] It should be noted that Figure 1 the arrow in

[0071] Further, referring to Figure 1 and Figure 2 , in this embodiment, the water purification device 1 further includes a water inlet valve 3, a first control valve 13, and a second control valve 12. The water inlet valve 3, the first control valve 13, and the second control valve 12 are all connected to the control device 2, and the control device 2 can be used to control the operation of the above-mentioned valve bodies.

[0072] The water inlet of the first flow path and the water inlet of the second flow path are both communicated with the water inlet valve 3. Specifically, one end of the water inlet valve 3 is communicated with the water inlet of the water purification device 1, and the other end of the water inlet valve 3 is respectively communicated with the water inlet of the first flow path and the water inlet of the second flow path. When the water inlet valve 3 is opened, external water is allowed to enter the water purification device 1; when the water inlet valve 3 is closed, external water is prohibited from entering the water purification device 1. The water inlet valve 3 can be a flow on-off valve or a flow valve with adjustable opening.

[0073] The first control valve 13 is arranged in the first flow path. When the first control valve 13 is opened, the water flowing into the water purification device 1 is allowed to flow through the first flow path into the washing chamber. When the first control valve 13 is closed, the water flowing into the water purification device 1 is prohibited from flowing through the first flow path into the washing chamber. The first control valve 13 can be a flow on-off valve or a flow valve with adjustable opening.

[0074] The second control valve 12 is arranged in the second flow path. Specifically, the second control valve 12 can be arranged between the filtration module 11 and the water inlet valve 3. When the second control valve 12 is opened, the water flowing into the water purification device 1 is allowed to flow through the filtration module 11 in the second flow path for filtration and then enter the washing chamber. When the second control valve 12 is closed, the water flowing into the water purification device 1 is prohibited from flowing through the filtration module 11 in the second flow path for filtration and then entering the washing chamber. The second control valve 12 can be a flow on-off valve or a flow valve with adjustable opening.

Specifically, the water flowing through the flow meter 4 can generate a pulse signal, and the control device 2 can determine the water flow rate flowing through the first flow path and / or the second flow path according to the number of generated pulses.

[0076] Further, in this embodiment, referring to Figure 2, the water purification device 1 may further include a turbidity sensor 5, which may be disposed at the water outlet of the second flow path to detect the turbidity value of the water discharged after filtration by the filtration module 11. The turbidity sensor 5 is connected to the control device 2, and the control device 2 can obtain the data detected by the turbidity sensor 5.

[0077] Further, in the embodiment of the present invention, referring to Figure 2 , the control device 2 of the washing device includes: a processor 1001 (such as a CPU) and a memory 1002, etc. The processor 1001 is connected to the memory 1002 through a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0078] Those skilled in the art can understand that Figure 2 the device structure shown in

[0079] does not constitute a limitation on the device, and may include more or fewer components than shown in the figure, or combine some components, or arrange different components. Figure 2 As shown in Figure 2 , the memory 1002, as a computer-readable storage medium, may include a control program for the washing device. In the

[0080] device shown, the processor 1001 can be used to call the control program for the washing device stored in the memory 1002 and execute the relevant step operations of the control method for the washing device in the following embodiments.

[0081] The embodiment of the present invention also provides a control method for a washing device, which is applied to the above-mentioned washing device. Figure 3 Referring to

[0082] , an embodiment of the control method for the washing device of the present application is proposed. In this embodiment, the control method for the washing device includes:

[0083] Step S10, obtaining the water inlet mode of the washing device;

[0084] The water inlet mode is specifically a mode of the washing device that characterizes whether the water inlet of the washing cavity has a filtration requirement. Different water inlet modes characterize different filtration requirements (such as the need for filtration, no need for filtration, the filtration intensity when filtration is required, etc.).

[0085] The water inlet mode can be determined according to the parameters set by the user, or can be determined according to the operating state corresponding to the washing cavity and / or the water quality in the washing device.

[0086] Step S20: Determine a target flow path in the first flow path and the second flow path according to the water inlet mode;

[0087] Different water inlet modes can correspond to different target flow paths. The target flow path corresponding to the water inlet mode can be one of the first flow path and the second flow path, or the target flow path corresponding to the water inlet mode can also include both the first flow path and the second flow path at the same time.

[0088] In this embodiment, one of the first flow path and the second flow path is determined as the target flow path according to the water inlet mode. Specifically, when the water inlet mode is the first mode, the first flow path is determined as the target flow path; when the water inlet mode is the second mode, the second flow path is determined as the target flow path; wherein, the first mode is a mode in which the washing cavity does not have a water inlet filtration requirement, and the second mode is a mode in which the washing cavity has a water inlet filtration requirement. Based on this, it is possible to select whether to filter the water inlet of the washing cavity by using the filtration module according to the actual water inlet requirement of the washing cavity, so as to filter the water through the filtration module to reduce the impurities in the washing water while ensuring that the water inlet mode can meet the actual use requirements.

[0089] In other embodiments, the target flow path corresponding to the water inlet mode can be one of the first flow path and the second flow path, or can also include both the first flow path and the second flow path at the same time. For example, when the water inlet mode is the first mode as described above, the first flow path is determined as the target flow path. When the water inlet mode is the first sub-mode, the second flow path is determined as the target flow path; when the water inlet mode is the second sub-mode, the first flow path and the second flow path are determined as the target flow paths. The first sub-mode and the second sub-mode here are sub-modes included in the second mode as described above, and the filtration intensity corresponding to the first sub-mode is greater than the filtration intensity corresponding to the second sub-mode.

[0090] Step S30: Control the water purification device to introduce the water flowing into the water purification device into the washing cavity through the target flow path.

[0091] In this embodiment, the water purification device includes a first control valve provided in the first flow path and a second control valve provided in the second flow path. When the target flow path is the first flow path, the first control valve can be controlled to open and the second control valve can be controlled to close, and all the water flowing into the water purification device flows through the first flow path directly into the washing chamber; when the target flow path is the second flow path, the first control valve can be controlled to close and the second control valve can be controlled to open, and all the water flowing into the water purification device flows through the second flow path and enters the washing chamber after being filtered by the filtration module; when the target flow path includes the first flow path and the second flow path, the first control valve can be controlled to open and the second control valve can be controlled to open, and a part of the water flowing into the water purification device flows through the first flow path directly into the washing chamber, and another part of the water flowing into the water purification device flows through the second flow path and enters the washing chamber after being filtered by the filtration module.

[0092] In other embodiments, the water purification device may include a three-way valve connecting the water inlet of the water purification device, the water inlet of the first flow path, and the water inlet of the second flow path. The three-way valve has a first valve position and a second valve position. When the target flow path is the first flow path, the three-way valve can be controlled to operate in the first valve position, so that all the water flowing into the water purification device flows through the first flow path and then enters the washing chamber; when the target flow path is the second flow path, the three-way valve can be controlled to operate in the second valve position, so that all the water flowing into the water purification device flows through the second flow path and is filtered before entering the washing chamber.

[0093] A control method for a washing device proposed in an embodiment of the present invention is based on a washing device internally provided with a water purification device and a washing chamber. The water purification device is provided with a first flow path for external water to pass through directly and a second flow path for filtering external water. This method selects a target flow path from the first flow path and the second flow path based on the water inlet mode of the washing device, and controls the water purification device to introduce external water into the washing chamber through the determined target flow path. In this solution, a water purification device having both a first flow path and a second flow path is added to the washing device, so that the washing device no longer has only one water inlet mode of direct water inlet, but can select the water inlet mode according to actual needs. The second flow path in the water purification device can filter external water to reduce the impurities in the washing water in the washing chamber. Based on this, it is beneficial to improve the water quality of the washing water of the washing device while ensuring that the water inlet mode of the washing chamber meets the actual needs, and effectively improves the washing effect and service life of the washing device.

[0094] Further, in an implementation manner of this embodiment, referring to Figure 4 , step S10 includes:

[0095] Step S11, obtaining a first turbidity value on the water outlet side of the filtration module;

[0096] Specifically, the first turbidity value here can be obtained by real-time obtaining the data detected by a turbidity sensor provided on the water outlet side of the filtration module.

[0097] Specifically, the steps of S11 here can be executed when the second control valve is in the open state. For example, after the above step S30, when the target flow path includes the second flow path, the process can return to execute step S11.

[0098] Step S12, when the first turbidity value is greater than the set turbidity value, determine that the first mode is the water inlet mode;

[0099] Step S13, when the first turbidity value is less than or equal to the set turbidity value, determine that the second mode is the water inlet mode.

[0100] It should be noted that the order of execution of step S12 and step S13 here is not specifically limited.

[0101] The set turbidity value is specifically a turbidity critical value preset for distinguishing whether the filtration module on the second flow path has reached the end of its service life. When the first turbidity value is greater than the set turbidity value, it indicates that the filtration module has reached the end of its service life; when the second turbidity value is less than or equal to the set turbidity value, it indicates that the filtration module has not reached the end of its service life.

[0102] In this embodiment, in the above manner, when the filtration module on the second flow path has not reached the end of its service life, the filtration module is used to filter the water entering the water purification device, thereby effectively reducing the impurities in the water entering the washing cavity and effectively improving the washing effect and service life of the washing device; when the filtration module on the second flow path has reached the end of its service life, the filtration module is not used to filter the water flowing into the water purification device, thereby preventing excessive impurities on the filtration module from causing secondary pollution to the water entering the washing cavity, effectively ensuring the water quality of the washing water, and effectively improving the washing effect and service life of the washing device.

[0103] Further, in this embodiment, after step S11, it further includes: when the first turbidity value is less than or equal to the set turbidity value and the washing cavity is in a preset operation stage, execute the step of determining that the second mode is the water inlet mode; wherein, the preset operation stage includes a self-cleaning stage, a sterilization stage or a rinsing stage. The preset operation stage is specifically a stage where the water in the washing cavity needs to be heated. In this embodiment, the washing cavity being in a preset operation stage such as the self-cleaning stage, the sterilization stage or the rinsing stage indicates that the probability of scale formation due to poor water quality in the washing cavity is relatively high. Therefore, when the filtration module has not reached the end of its service life and has a better filtration effect and the washing cavity is in the preset operation stage, the filtration module of the second flow path is used to filter the water, thereby further effectively improving the washing effect and service life of the washing device.

[0104] Wherein, when the first turbidity value is less than or equal to the set turbidity value and the washing chamber is not in the preset operation stage, it can be determined that the first mode is the water inlet mode, or it can be determined that the second mode is the water inlet mode, or it can be determined that both the first mode and the second mode are the water inlet modes.

[0105] Further, in this embodiment, during or after the execution of step S12, a replacement prompt message corresponding to the filtration module is sent to the control application of the washing device based on a wireless communication connection, so that the control application outputs the replacement prompt message; and / or, the prompt module on the washing device is controlled to output the replacement prompt message corresponding to the filtration module. Specifically, the terminal installed with the control application can be determined as the target terminal (such as a mobile phone, a tablet computer, etc.). The target terminal is wirelessly communicatively connected to the server, and the server is wirelessly communicatively connected to the washing device. Based on this, the replacement prompt message can be uploaded to the server, and the server can send the replacement prompt message to the target terminal where the control application is located, so that the replacement prompt message is output in the control application on the target terminal. The prompt module on the washing device can be a display screen provided on the washing device, or a voice broadcast module provided on the washing device, etc. By outputting the replacement prompt message through the target terminal and / or the prompt module on the washing device, the user can be reminded to replace the filtration module of the water purification device in the washing device, so that the user can replace the filtration module in time to ensure the filtration effect of the water purification device, so as to ensure the effective improvement of the water quality flowing into the washing chamber, thereby effectively improving the washing effect and the service life of the washing device.

[0106] Further, in another implementation manner of this embodiment, step S10 includes: obtaining the setting information of the water inlet mode input by the control application of the washing device based on a wireless communication connection; determining the water inlet mode according to the setting information. The user can control the control application to input the setting information here according to the actual water inlet requirement. Specifically, the setting information can be the selection information of the above first mode and second mode, and one or both of the first mode and the second mode can be selected as the water inlet mode according to the setting information. Based on this, it can be ensured that the water inlet mode of the washing device can meet the actual use requirements of the user.

[0107] Further, in other embodiments, when it is determined that the second mode is the water inlet mode according to the setting information, the above step S11 can be executed after step S30. Or, when the first turbidity value is less than or equal to the set turbidity value and the washing chamber is not in the preset operation stage, the steps of "obtaining the setting information of the water inlet mode input by the control application of the washing device based on a wireless communication connection; determining the water inlet mode according to the setting information" can be executed here.

[0108] Further, based on the above embodiment, another embodiment of the control method of the washing device of the present application is proposed. In this embodiment, refer to Figure 5, the step S20 further includes:

[0109] Step S21, when the water inlet mode is the second mode, obtain the turbidity change value between the water inlet side and the water outlet side of the filtration module;

[0110] Specifically, the third turbidity value of the water inlet side of the filtration module and the fourth turbidity value of the water outlet side of the filtration module can be obtained, and the difference between the third turbidity value and the fourth turbidity value is determined. In this embodiment, the absolute value of the determined difference is used as the turbidity change value; in other embodiments, the determined difference can also be directly used as the turbidity change value.

[0111] Step S22, when the turbidity change value is less than the set turbidity change threshold, execute the step of determining the second flow path as the target flow path;

[0112] Step S23, when the turbidity change value is greater than or equal to the set turbidity change threshold, determine the first flow path and the second flow path as the target flow path.

[0113] It should be noted that the water turbidity value in the washing cavity corresponding to defining the second flow path as the target flow path is the first water turbidity value, and the water turbidity value in the washing cavity corresponding to defining the first flow path and the second flow path as the target flow path is the second water turbidity value. Both the first water turbidity value and the second water turbidity value are less than the preset turbidity threshold, and the preset turbidity threshold is the maximum water turbidity value allowed in the washing cavity when the washing effect and service life reach the target requirements.

[0114] The set turbidity change threshold is specifically a critical value for distinguishing the filtering effect of the filtration module. When the turbidity change value is less than the set turbidity change threshold, the smaller turbidity change of the water flow before and after passing through the filtration module indicates that the filtering effect of the filtration module is poor. At this time, all the water entering the water purification device passes through the filtration module and then enters the washing cavity, which is beneficial to ensuring better water quality in the washing cavity and effectively improving the washing effect and the service life of the washing equipment; when the turbidity change value is greater than or equal to the set turbidity change threshold, the larger turbidity change of the water flow before and after passing through the filtration module indicates that the filtering effect of the filtration module is better. At this time, a part of the water entering the water purification device can directly enter the washing cavity without passing through the filtration module, and the other part of the water entering the water purification device passes through the filtration module and then enters the washing cavity. Based on this, the water flowing out from the first flow path and the second flow path can ensure better water quality in the washing cavity after mixing, which is beneficial to extending the service life of the filtration module while achieving better water quality in the washing cavity and effectively improving the washing effect and the service life of the washing equipment.

[0115] Further, in this embodiment, based on the above step S20, referring to Figure 5 , step S30 includes:

[0116] Step S31, when the first flow path and the second flow path are the target flow paths, determine the target flow ratio according to the turbidity change value. The target flow ratio is the proportional relationship between the first water flow rate of the first flow path and the second water flow rate of the second flow path, and the second water flow rate is greater than the first water flow rate.

[0117] Different turbidity change values correspond to different target flow ratios. The proportion of the first water flow rate in the target flow ratio is positively correlated with the turbidity change value. That is, the greater the turbidity change value, the greater the proportion of the first water flow rate. It should be noted that no matter how the target flow ratio changes, the second water flow rate corresponding to the target flow ratio is always greater than the first water flow rate, so as to ensure that the water quality flowing into the washing cavity can meet the target requirements.

[0118] Step S32, control the water purification device to introduce the water flowing into the water purification device into the washing cavity through the first flow path and the second flow path respectively according to the target flow ratio.

[0119] Specifically, in this embodiment, a first control valve is provided in the first flow path, and a second control valve is provided in the second flow path. The first target opening degree of the first control valve and the second target opening degree of the second control valve can be determined according to the target flow ratio, and the first control valve is controlled to operate at the first opening degree, and the second control valve is controlled to operate at the second opening degree.

[0120] In this embodiment, when the first flow path and the second flow path are both the target flow paths, the target flow ratio is determined based on the turbidity change value, and the water volumes flowing through the first flow path and the second flow path are controlled according to the target flow ratio, so as to ensure that the water quality after the water from the first flow path and the water from the second flow path are mixed in the washing cavity can accurately meet the target requirements, thereby effectively improving the washing effect and the service life of the washing equipment.

[0121] In other embodiments, when the first flow path and the second flow path are the target flow paths, the water purification device can also be controlled to introduce the water flowing into the water purification device into the washing cavity through the first flow path and the second flow path respectively according to a preset fixed flow ratio.

[0122] Further, based on any of the above embodiments, another embodiment of the control method of the washing equipment of the present application is proposed. In this embodiment, referring to Figure 6 , the water purification device further includes a water inlet valve, a first control valve and a second control valve. The water inlets of the first flow path and the second flow path are both communicated with the water inlet valve. The first control valve is provided in the first flow path, and the second control valve is provided in the second flow path. The step S30 includes:

[0123] Step S301, when the target flow path includes the first flow path, control the first control valve to open, and after an interval of a first duration, control the water inlet valve to open, so that the water flowing into the water purification device sequentially passes through the water inlet valve and the first control valve and enters the washing chamber;

[0124] Step S302, when the target flow path includes the second flow path, control the second control valve to open, and after an interval of a second duration, control the water inlet valve to open, so that the water flowing into the water purification device sequentially passes through the water inlet valve, the second control valve and the filtration module and enters the washing chamber.

[0125] The first duration and the second duration may be the same or different. The first duration and the second duration may be preset fixed values, or may be values determined according to the actual operating conditions of the washing equipment. In this embodiment, the second duration may be greater than the first duration to effectively protect the filtration module and extend the service life of the filtration module.

[0126] Wherein, when the target flow path includes both the first flow path and the second flow path, the first control valve can be controlled to open, the second control valve can be controlled to open, and after an interval of the larger of the first duration and the second duration, the water inlet valve can be controlled to open.

[0127] In this embodiment, the first control valve and the second control valve are opened prior to the water inlet valve, which is beneficial to avoid damage or loosening of the first control valve and the second control valve or the first flow path and the second flow path due to excessive water pressure, thereby effectively protecting the water purification device, improving the water quality in the washing chamber and extending the service life of the water purification device.

[0128] Further, after step S302, it further includes: obtaining a second turbidity value on the water outlet side of the filtration module; determining a first target opening degree of the second control valve and a second target opening degree of the water inlet valve according to the second turbidity value; controlling the second control valve to operate at the first target opening degree, and controlling the water inlet valve to operate at the second target opening degree.

[0129] Different second turbidity values correspond to different first target opening degrees and second target opening degrees. Among them, the larger the second turbidity value, the larger the second target opening degree can be. Specifically, the target opening degree difference between the first target opening degree and the second target opening degree can be determined according to the second turbidity value, and the first target opening degree and the second target opening degree can be determined according to the target opening degree difference. Or, the first target opening degree and the second target opening degree here can be directly queried from a preset mapping table through the second turbidity value.

[0130] In this embodiment, since different second turbidity values indicate different amounts of dirt on the filtration module, and different amounts of accumulated dirt on the filtration module are affected differently by the water pressure. Based on this, controlling the operation of the second control valve and the inlet valve by combining the first target opening and the second target opening determined according to the second turbidity value is beneficial to improving the filtration effect of the filtration module and ensuring that the water quality entering the washing chamber through the second flow path can meet the requirements.

[0131] Further, based on any of the above embodiments, another embodiment of the control method of the washing device of the present application is proposed. In this embodiment, referring to Figure 7 , after the step S30, the following is further included:

[0132] Step S40, detecting the number of pulses corresponding to the water flow rate flowing through the target flow path;

[0133] Specifically, the number of pulses here can be obtained by acquiring the pulse number detected by the flow meter provided on the target flow path. When the first flow path and the second flow path are the target flow paths, the sum of the first pulse number detected by the flow meter provided on the first flow path and the second pulse number detected by the flow meter provided on the second flow path can be used as the number of pulses here.

[0134] Step S50, when the number of pulses is greater than the set number of pulses, controlling the water purification device to stop introducing the water flowing into the water purification device into the washing chamber.

[0135] The set number of pulses is specifically determined according to the target water inflow of the washing chamber. The target water inflow is positively correlated with the set number of pulses.

[0136] Specifically, in this embodiment, the water purification device further includes an inlet valve, a first control valve, and a second control valve. The water inlets of the first flow path and the second flow path are both communicated with the inlet valve. The first control valve is provided on the first flow path, and the second control valve is provided on the second flow path. The step of controlling the water purification device to stop introducing the water flowing into the water purification device into the washing chamber includes: when the target flow path includes the first flow path, controlling the inlet valve to close, and controlling the first control valve to close after an interval of a third time period; when the target flow path includes the second flow path, controlling the inlet valve to close, and controlling the second control valve to close after an interval of a fourth time period. The third time period and the fourth time period here can be the same or different. The third time period and the fourth time period can be preset fixed parameters, or values determined according to the current operating conditions of the washing device. In this embodiment, the fourth time period is greater than the third time period. Closing the inlet valve first and then closing the first control valve and the second control valve here is beneficial to ensuring that the water pressure does not damage the first control valve, the second control valve, and their pipelines, is beneficial to protecting the devices, improving the water quality of the washing water, and extending the service life of the water purification device.

[0137] In this embodiment, the amount of water flowing through the target flow path is characterized based on the number of pulses. When the number of pulses is greater than the set number of pulses, water introduction into the washing chamber is automatically stopped, thereby improving the water quality in the washing chamber while ensuring that the water inflow into the washing chamber can meet the usage requirements.

[0138] In other embodiments, the duration for which the water purification device introduces the water flowing into the water purification device into the washing chamber through the target flow path can also be obtained. When the duration is greater than or equal to the set duration, the water purification device is controlled to stop introducing the water flowing into the water purification device into the washing chamber.

[0139] Further, based on any of the above embodiments, after step S30, it further includes: when the target flow path includes the first flow path, if the washing operation in the washing chamber ends, the drainage module corresponding to the washing chamber is controlled to remain open for a preset duration to drain all the water in the washing chamber. Specifically, the target flow path including the first flow path indicates that water directly enters the washing chamber without filtration. Delaying the closing of the drainage module after the washing operation in the washing chamber ends helps to avoid the residue of water with poor quality in the washing chamber, fully drain the water in the washing chamber, and effectively extend the service life of the washing device.

[0140] In addition, an embodiment of the present invention also provides a computer-readable storage medium, on which a control program for a washing device is stored. When the control program for the washing device is executed by a processor, the relevant steps of any of the above embodiments of the control method for the washing device are implemented.
